# Ecstatic [![build status](https://secure.travis-ci.org/jfhbrook/node-ecstatic.png)](http://travis-ci.org/jfhbrook/node-ecstatic)

![](http://imgur.com/vhub5.png)

A simple static file server middleware. Use it with a raw http server or
express/connect!

# Examples:

## express 3.0.x

``` js
var http = require('http');
var express = require('express');
var ecstatic = require('ecstatic');

var app = express();
app.use(ecstatic({ root: __dirname + '/public' }));
http.createServer(app).listen(8080);

console.log('Listening on :8080');
```

## stock http server

``` js
var http = require('http');
var ecstatic = require('ecstatic');

http.createServer(
  ecstatic({ root: __dirname + '/public' })
).listen(8080);

console.log('Listening on :8080');
```
### fall through
To allow fall through to your custom routes:

```js
ecstatic({ root: __dirname + '/public', handleError: false })
```

# API:

## ecstatic(opts);

Pass ecstatic an options hash, and it will return your middleware!

```js
var opts = {
             root               : __dirname + '/public',
             port               : 8000,
             baseDir            : '/',
             cache              : 3600,
             showDir            : true,
             showDotfiles       : true,
             autoIndex          : false,
             humanReadable      : true,
             headers            : {},
             si                 : false,
             defaultExt         : 'html',
             gzip               : false,
             serverHeader       : true,
             contentType        : 'application/octet-stream',
             mimeTypes          : undefined,
             handleOptionsMethod: false
           }
```

If `opts` is a string, the string is assigned to the root folder and all other
options are set to their defaults.

### `opts.root`

`opts.root` is the directory you want to serve up.

### `opts.port`

`opts.port` is the port you want ecstatic to listen to. Defaults to 8000.

### `opts.baseDir`

`opts.baseDir` is `/` by default, but can be changed to allow your static files
to be served off a specific route. For example, if `opts.baseDir === "blog"`
and `opts.root = "./public"`, requests for `localhost:8080/blog/index.html` will
resolve to `./public/index.html`.

### `opts.cache`

Customize cache control with `opts.cache` , if it is a number then it will set max-age in seconds.
Other wise it will pass through directly to cache-control. Time defaults to 3600 s (ie, 1 hour).

If it is a function, it will be executed on every request, and passed the pathname.  Whatever it returns, string or number, will be used as the cache control header like above.

### `opts.showDir`

Turn **off** directory listings with `opts.showDir === false`. Defaults to **true**.

### `opts.showDotfiles`

Exclude dotfiles from directory listings with `opts.showDotfiles === false`. Defaults to **true**.

### `opts.humanReadable`

If showDir is enabled, add human-readable file sizes. Defaults to **true**.
Aliases are `humanreadable` and `human-readable`.

### `opts.headers`

Set headers on every response. `opts.headers` can be an object mapping string
header names to string header values, a colon (:) separated string, or an array
of colon separated strings.

`opts.H` and `opts.header` are aliased to `opts.headers` so that you can use
`-H` and `--header` options to set headers on the command-line like curl:

``` sh
$ ecstatic ./public -p 5000 -H 'Access-Control-Allow-Origin: *'
```

### `opts.si`

If showDir and humanReadable are enabled, print file sizes with base 1000 instead
of base 1024. Name is inferred from cli options for `ls`. Aliased to `index`, the
equivalent option in Apache.

### `opts.autoIndex`

Serve `/path/index.html` when `/path/` is requested.
Turn **off** autoIndexing with `opts.autoIndex === false`. Defaults to **true**.

### `opts.defaultExt`

Turn on default file extensions with `opts.defaultExt`. If `opts.defaultExt` is
true, it will default to `html`. For example if you want a request to `/a-file`
to resolve to `./public/a-file.html`, set this to `true`. If you want
`/a-file` to resolve to `./public/a-file.json` instead, set `opts.defaultExt` to
`json`.

### `opts.gzip`

Set `opts.gzip === true` in order to turn on "gzip mode," wherein ecstatic will
serve `./public/some-file.js.gz` in place of `./public/some-file.js` when the
gzipped version exists and ecstatic determines that the behavior is appropriate.

### `opts.serverHeader`

Set `opts.serverHeader` to false in order to turn off setting the `Server` header
on all responses served by ecstatic.

### `opts.contentType`

Set `opts.contentType` in order to change default Content-Type header value.
Defaults to **application/octet-stream**.

### `opts.mimeTypes`

Add new or override one or more mime-types. This affects the HTTP Content-Type header.
Can either be a path to a [`.types`](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types) file or an object hash of type(s).

    ecstatic({ mimeType: { 'mime-type': ['file_extension', 'file_extension'] } })

### `opts.handleError`

Turn **off** handleErrors to allow fall-through with `opts.handleError === false`, Defaults to **true**.

### `opts.weakEtags`

Set `opts.weakEtags` to true in order to generate weak etags instead of strong etags. Defaults to **false**. See `opts.weakCompare` as well.

### `opts.weakCompare`

Turn **on** weakCompare to allow the weak comparison function for etag validation. Defaults to **false**.
See https://www.ietf.org/rfc/rfc2616.txt Section 13.3.3 for more details.

### `opts.handleOptionsMethod`

Set handleOptionsMethod to true in order to respond to 'OPTIONS' calls with any standard/set headers. Defaults to **false**. Useful for hacking up CORS support.

### `opts.cors`

This is a **convenience** setting which turns on `handleOptionsMethod` and sets the headers **Access-Control-Allow-Origin: \*** and **Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since**. This *should* be enough to quickly make cross-origin resource sharing work between development APIs. More advanced usage can come either from overriding these headers with the headers argument, or by using the `handleOptionsMethod` flag and then setting headers "manually." Alternately, just do it in your app using separate middlewares/abstractions.

Defaults to **false**.

## middleware(req, res, next);

This works more or less as you'd expect.

### ecstatic.showDir(folder);

This returns another middleware which will attempt to show a directory view. Turning on auto-indexing is roughly equivalent to adding this middleware after an ecstatic middleware with autoindexing disabled.

### `ecstatic` command

to start a standalone static http server,
run `npm install -g ecstatic` and then run `ecstatic [dir?] [options] --port PORT`
all options work as above, passed in [optimist](https://github.com/substack/node-optimist) style.
`port` defaults to `8000`. If a `dir` or `--root dir` argument is not passed, ecsatic will
serve the current dir. Ecstatic also respects the PORT environment variable.

# Tests:

Ecstatic has a fairly extensive test suite. You can run it with:

```sh
$ npm test
```

# Contribute:

Without outside contributions, ecstatic would wither and die! Before
contributing, take a quick look at the contributing guidelines in
[./CONTRIBUTING.md](./CONTRIBUTING.md) . They're relatively painless, I promise.
For Windows users, it is especially important to read the [./CONTRIBUTING.md](./CONTRIBUTING.md)
section as you can **not** clone ecstatic without changing some settings in git.
